In accordance with the European commission's ecological standards for the
control of acrylonitrile residues in acrylic fibers, a headspace solid-phase extraction
and chromatography-mass spectrometry (hs-smpe-gc /MS) technique was used to
establish a method for the determination of acrylonitrile residues in acrylic fibers. The
detection limit of this method is less than 0.5 mg/kg, and the recovery is between 91.9
% and 97.7 %.
